With the nuclear men - I think nah. Who would bother. It is not a strange co-incidence, as if there are many of them left in the country who can build a nuclear power station :o)) All old Soviet anyway, not much choice :o) There was some equipment bought for Petrozavodsk, which they flew to check, what is bought. Ordinary.
One would say don't fly 31 year old TU, that spent 1.5 years standing still before the flight, and is not on his regular flight, on tops, but is fished out from nowhere last minute replacing the line standard one (Bombardier), in fog, about which the control tower man told his wife going to work
"I won't allow tonight to land even a crow", with the pilot who hasn't been on holidays for 3 years doing charter flights, and other interesting details emerging.
